What this lesson teaches
World War I (1914-1918) grew out of rival alliances, nationalism, militarism, and imperial competition, then became a deadly stalemate of trench warfare and new weapons. Its peace settlement redrew the map of Europe and left resentments that fueled future conflict.
Worked example
The 1919 Treaty of Versailles forced Germany to accept blame for the war and pay heavy reparations, a punishment many Germans bitterly resented in the years that followed.
Practice questions
- Name two long-term causes of World War I.
- Explain why trench warfare produced such enormous casualties.
- Analyze how the terms of the Treaty of Versailles may have set the stage for later conflict.
